A green light is incident from the water to the air - water interface at the critical angle `(theta)`. Select the correct statement.

A

The entire spectrum of visible light will come out of the water at an angle of `90^(@)` to the normal

B

The spectrum of visible light whose frequency is less than that of green light will come out of the air medium

C

The spectrum of visible light whose frequency is more than that of green light will come out to the air medium

D

The entire spectrum of visible light will come out of the water at various angles to the normal

Text Solution

Verified by Experts

The correct Answer is:
B
Since , sin `i_(c) = (1)/(n) and lambda prop (1)/(n)`
for greater ` lambda ` or lesser frequency n is less
so, `i_(c)` would be more
and they will not suffer reflection and come out at angles less than `90^(@)`
